localStorage key the scroll group state is persisted under: every group's Scripture reference.
Named here rather than in the host because two processes spell it: main's host, which owns the
store, and the renderer, whose one-time handover reads the copy left in its own localStorage
from when a renderer held this state. Those are two different stores under one key name, and the
handover only finds anything if the name stays identical in both.
